Nonin 9590-BK Onyx Vantage 9590 Finger Oximeter, 359mm x 330mm x 323mm, Black

Been using this brand for years and nothing seems to compare definitely recommend

Highly recommend. I calibrated it against my Apple Watch and the two were identical. I suppose they both could be identically wrong!!! :)

I've had cheaper oximetry before and got this having read the reviewsI can see little difference between this and the cheap ones but I accept that it is must be moredependable when the comparative reports have found thatI see children and adults but in infants the probe is too big and results are temperamental+++ and I have to use a more expensive oximetrr belonging to the out of hours centre these cost maybe £500-£600 , hence not 5 stars

A flimsy product with spring loaded joint that are weak and will break; item powers up and down as the contact points are not properly fitted. And this is a new item. Please check return policy with Amazon if you decide to buy as you will not be able to return it despite UK distant selling laws

Dependable accurate (in comparison with £600+ products) for professional use (and handier to carry in bag). Like all sensors needs warm hands. Kids under 8 months fail to register due to size, even big toe but not a criticism for its accuracy to all other age groups.

This has been very useful to a relative who is on oxygen 24 hours a day. He has been able to ensure he is getting the correct amount and it has helped in conversations with the hospital consultant.It is also extremely easy to use.

Excellent product and excellent support team!

The stars reflect experience so far. Yet to use in the air. Five star customer service for theuninitiated. Tested in chemist and everything is fine. Thank you Nonin.
